Template-Type: ReDIF-Paper 1.0 Title: Regulation of an Open Access Essential Facility Author-Name: Axel Gautier Author-Name: Manipushpak Mitra Author-Email: Classification-JEL: D82, H54, L11, L51 Keywords: Regulation, Railways, Network, Entry, Competition, Access charge, Asymmetric Information Abstract: In this paper we consider the problem of regulating an open access essential facility. A vertically integrated firm owns an essential input and operates on the downstream market under the roof of a regulatory mechanism. There is a potential entrant in the downstream market. Both competitors use the same essential input to provide the final services to the consumers. The regulator designs a mechanism that guarantees financing of the essential input and adequate competition in the downstream market. We consider a regulatory mechanism that grants non-discriminatory access of the essential facility to a competitor. We show that this mechanism is welfare improving but it generates inefficient entry. That is a more efficient competitor may stay out of the market or a less efficient competitor may enter the market.
